About Me

SnowPro Core Certified Analytics Engineer specializing in scalable data transformation, GTM analytics, and self-service analytics.

I lead analytics engineering at MyBambu, where I maintain 30+ production dbt models processing 50M+ daily records while reducing Snowflake costs by 60% ($200K annually). I built GTM infrastructure analyzing $1.7M quarterly ad spend with multi-touch attribution, identifying $400K+ optimization opportunities.

My expertise spans implementing Cortex AI for natural language data queries, pioneering RAG systems with 12% better retrieval than OpenAI, and architecting dimensional models achieving sub-second dashboard response times.

Previously, I managed 10TB SAP migrations at Accenture and recovered $68K at Infosys, earning the INSTA Award (top 1%).
